Abstract
An original reading apparatus includes an original tray. A conveyance unit conveys an original of an original bundle on the original tray. A reading unit reads the original conveyed. A first detection unit detects a first length of the original in a principal scanning direction. A second detection unit detects a second length of the original bundle in an auxiliary scanning direction. A third detection unit detects the original conveyed. A prediction unit predicts an original size by selecting from candidates corresponding to the first length in a first prediction mode, or by determining based on the first and second lengths in a second prediction mode. A specifying unit specifies the original size based on the first length and a length in the auxiliary scanning direction detected by the third detection unit. A change unit changes the prediction mode when the predicted original size differs from the specified original size.
